THREAD HOLDER AND CUTTER.

Application filed July 20,

T0 alt whom it may concern:

Be it known that we, JANE H. Beans and dorm iinnnnsoiv, both citizens ofthe United States, and residents of Middletown, in the county oflliiddlesex and State of Connectiout, have invented a new and ImprovedThread Holder and Cutter, of which thefollowing is a full, clear, andexact description.

This invention relates to a thread holder and cutter for use inconjunction with spools.

After a spool of thread has been opened and a portion of the threadunwound there is no means for fixing the end of the thread and when thespool is thrown into a basket or other container the tiread unwinds andbecomes entangled with the other spools or other articles.

The object of this invention is to provide a device that may be attachedto spools, which holds the end or" the thread and which has inconjunction therewith means for cutting the thread. 7

This object is accomplished by clamping two disk members together andproviding in conjunction with the clamping means spring means forattaching the disk members to the spool. A thread cutting means isprovided in conjunction with one of the disks.

This and other objects of the invention will be more clearly understoodfrom the following detailed description and accompanying drawings.

Figure 1 is a top plan view of the thread cutter and holder;

Figure 2 is a cross section along the line 2-2, Figure 1;

Figure 3 is a cross section along the line 3-3, Figure 2;

Figure 4 is a cross section along the line 4-4, Figure 2;

Figure 5 is a cross section through the thread holder and cutter showinga modification of the spring means used for attaching it to the spool;and

Figure 6 is a cross section along the line 6-6, Figure 5.

Referring to the above-mentioned drawings, the spool 10 has thread 11wound thereon. An opening 12, which extends from end to end of the spool10, is provided. The thread holder consists of two disks 13 V and 14:which have openings 15 and 16 1921. Serial No. 486,199.

through their centers. The lower disk is fiat and has a portion of theedge bent up forming a blade 17. This blade is sharpened, presenting aknife edge 18 which serves for cutting the thread. The upper disk iscurved to the shape of a saucer and is mounted, on the disk 17 with theconcave side upward so that the opening 15 coincides with the opening16. A piece of sheet metal 19 is folded to a cylindrical shape about thesize of the cylindrical opening 12 the spool, and a. plurality oftongues 20 are cut in its upper end. Every second one of these tongues20 are bent outwards forming shoulders. The remaining tongues areprojected through the openings in the disks l3 and 14; until theshoulders come in contact with the disk 14. Thus the tongues extendingthrough the openings are bent over into contact with the disk 13 thusclamping the disks together. The bottom portion of the sheet of metal iscut formin long tongues 21 which are bent outward. These tongues formspring means for detaching the thread holder and cutter to the spool.Integral with the disk 14 is a projection 22.

A modification of the spring means for connecting the thread cutter andholder to the spool is shown in Figure 5. In this case the sheet ofmetal 19 is rolled into a cylindrical form with a space between itsedges. The upper end is cut in tongues as already described and attachedto the disk members. In attaching it to the disk members, the upper endis pressed inward, making it of a slightly smaller diameter than thelower end. In order to insert the lower end into the spool the sideshave to be pressed together and they tend to return to their normalposition and thus provide a spring means for connecting the device tothe spool.

Many other modifications of the spring means for connecting the threadholder and cutter to the spool may be made.

The operation of this device is as follows:

The spring means are pressed together and inserted in the opening 12 inthe spool. The device is then pushed home until the disk 1e comes incontact with the end of the spool. After the desired amount of threadhas been unwound from the spool the thread is brought into contact withthe projection 22 and drawn between the disks 13 and 14 and then it iscut off by means of the cutter 17. It will be seen that the end of thethread will remain beween the disks 13 and 14.

Claim.

A thread holder and cutter for use with spools, comprising a; flat diskperforated at its centre, said disk having a projection extendingoutward from one side and an upturned portion on the opposite sideforming a cutter, a hollow cylindrical spring 1 member provided withmeans on its upper end for clamping the disks together, and springmembers on its lower end for engag ing the spool to retain the threadhold and cutter in positionon the same.
